A vacuum cleaner includes a suctioning unit, a main body including a cyclone unit for separating dust from the air suctioned through the suctioning unit, a body forming a dust container for storing the dust separated by the cyclone unit, and a body cover for opening and closing the lower side of the body. A filter unit is arranged in the body for filtering air. An actuating unit is configured to move in the body along a space between the outside of the filter unit and the inner circumferential surface of the body.

A cleaner is disclosed. The cleaner may include a housing having an opening through which air is introduced into the housing. The cleaner may also include a filtering unit mounted in the inner space of the housing. The filtering unit may define a dust collection space between the filtering unit and the inner surface of the housing. In addition, the cleaning unit may be mounted to surround the filtering unit. A manipulation unit may raise or lower the cleaning unit within the dust collection space. Furthermore, brush protrusions may protrude from the cleaning unit toward the surface of the filtering unit.

A cleaner is disclosed. The cleaner includes: a housing having an introduction opening through which air is introduced; a filtering unit configured to be mounted in an inner space of the housing, and defining a dust collection space between the filtering unit and an inner surface of the housing; and a cleaning unit surrounding the filtering unit and configured to be raised and lowered. When the cleaning unit is in an initial position at least a portion of the cleaning unit is connected to an air introduction path extending from the introduction opening such that the cleaning unit guides a flow of introduced air. A guide edge extends from a lower portion of the cleaning unit toward a bottom of the dust collection space, and a surface of the guide edge facing the inner surface of the housing is inclined.

A cleaner is disclosed. The cleaner includes: a housing having an introduction opening through which air is introduced; a filtering unit configured to be mounted in an inner space of the housing, and defining a dust collection space between the filtering unit and an inner surface of the housing; and a cleaning unit configured to surround the filtering unit, and configured to be raised and lowered inside the dust collection space along with a manipulation unit, wherein, when the cleaning unit is in an initial position, at least a portion of the cleaning unit is connected to an air introduction path extending from the introduction opening to form a guide flow path to guide a flow of introduced air.

The present disclosure discloses a dust collector for a vacuum cleaner including a first cyclone installed within an outer case to filter out dust from air inhaled from an outside thereof and introduce the air from which dust has been filtered out into an inside thereof, a plurality of second cyclones accommodated in the inside of the first cyclone to separate fine dust from the air introduced to the inside of the first cyclone, and a cover member disposed to cover an inlet of the second cyclone, wherein cyclones disposed adjacent to each other among the first and the second cyclones limit a first space within the first cyclone, and the cover member forms a second space communicating with the first space between the inlet and the cover member, and a guide vane extended in a spiral shape along an inner circumference thereof is provided at the inlet to induce rotational flow in air introduced to an inside of the second cyclone through the first and the second space.

A cleaning robot system including a robot and a robot maintenance station. The robot includes a robot body, a drive system, a cleaning assembly, and a cleaning bin carried by the robot body and configured to receive debris agitated by the cleaning assembly. The robot maintenance station includes a station housing configured to receive the robot for maintenance. The station housing has an evacuation passageway exposed to a top portion of the received robot. The robot maintenance station also includes an air mover in pneumatic communication with the evacuation passageway and a collection bin carried by the station housing and in pneumatic communication with the evacuation passageway. The station housing and the robot body fluidly connect the evacuation passageway to the cleaning bin of the received robot. The air mover evacuates debris held in the robot cleaning bin to the collection bin through the evacuation passageway.

The present invention provides a dust collecting apparatus for a vacuum cleaner, comprising: a first cyclone installed in a first case and configured to separate dust from air introduced thereinto together with foreign substances and to discharge the separated dust to a first dust storage unit; a second cyclone mounted above the first cyclone and configured to separate fine dust from the air from which the dust is separated by the first cyclone and to discharge the separated fine dust to a second dust storage unit; a compression device configured such that at least a part thereof performs normal rotation in one direction and reverse rotation in the direction opposite to that of the normal rotation along the outer peripheral surface of a second case having the second dust storage unit therein to compress the dust stored in the first dust storage unit; a screw rotatably installed above the compression device and having a guide vane spirally extending along the outer periphery thereof to guide the collection of dust into the first dust storage unit; a driving unit that transmits a driving force to the compression device to selectively enable the normal rotation and the reverse rotation of the compression device; and a gear unit installed between the compression device and the screw to enable the screw to perform normal rotation while the compression device performs the normal rotation and the reverse rotation.

A cleaner includes a housing including a suction opening, a cyclone part configured to separate air and dust, and a dust bin configured to store dust separated from air in the cyclone part and a frame disposed to surround an axis of a cyclone flow of the cyclone part in the housing and configured to be movable between a first position and a second position in the housing, wherein the frame includes a first body disposed to face the suction opening at the first position and disposed to be inclined with respect to the axis of the cyclone flow, and an upper end of the first body is located to be the same as or higher than an upper end of the suction opening.
